ABRALWI W. HARRIS, OF PROVIDENCE, RHODE ISLAND.

RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,016, dated December21, 1897.

Application filed March 19,1897. Serial No. 628,273. (No model.)

2" 0 all whom it may concern.-

Be it known that I, ABRAM IV. HARRIS, of Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Ring-Spinning Machines; and I do hereby declarethat the following is a full, clear, and exact descrip tion thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to that class of spinningmachines known as ring-spinning frames, and is an improvement on the E. and A. WV. Harrispatent, No. 257,321.

It consists, mainly, in an improved method and means for holding therings and giving them the desired rotary. motion.

It is fully illustrated in the accompanying drawings.

Figure 1 is a front elevation of a part of each end and a portion of themiddle of a ring-frame. Fig. 2 is a top view of a ringrail andring-rotating devices. Fig.- 3 is a horizontal section of the lower parton line m a: in Fig. 1, showing the arrangement of the center and crossshafts, with the gearing for giving motion to the rings. elevation ofthe frame, showing the connection between the band-cylinder or mainshaft, with the center shaft that drives the rings. Fig. 5 represents aring-holder bearing separate. Fig. 7 is a vertical section ofring-holder on line 2 z in Fig. 6.

The object of the invention is to produce a simpler mode of giving therings the desired rotary motion instead of the intermittent or variablerotary motion described in the patent above referred to. The object inview in causing the rings to revolve is fully explained in said patent,and may be briefly stated as being for the purpose of reducing thefriction of the traveler on the ring and consequent drag on the yarn inspinning the finer numbers, especially at the time when the yarn iswinding on the smaller part of the bobbin or spindle and the draft onthe yarn is nearly in the direction of the center of the ring.

In the drawings, A is the machine-frame; D, the spindle-rail; O, thelower rail; F, the roller-beam; R, the center ring-driving shaft.

Fig. 4 is an end 'dle.

Fig. 6 is a top view of the ring-holden.

S S are the vertical ring-shafts. All those parts of a ring-spinningframe not described here, including such parts as the drawingrolls withtheir gears and devices for giving a vertical reciprocating motion tothe ring-rail, may be constructed in any of the ways usual in suchmachines, the object in omitting them being to simplify the drawings anddescription of the improvement, and both sides of the machine are alikein construction, though only one is described.

In this method I make a separate support foreach ring-holder to revolvein. (Shown in Fig. It consists of a ring at, having an opening in itinto which the ring-holder c, Fig. 6, is nicely fitted to revolvefreely. The ring a has alegson each side of proper length to elevate itsufficiently to receive the whirl d, attached to the ring-holder a,under it but above the ring-rail J, to which the support is attached bymeans of horizontal ears projecting out from the legs, through whichscrews 0 0 are put and screwed into the ring-rail. The support for thering-holder is placed across the opening in the rail through which thespindle and bobbin pass and is made adjustable by the enlargement of theholes in its ears through which the screws 0 pass, so it can be setexactly concentric with the spin- To allow the belt n to come in contactwith the whirls d on each side, the ears are set nearly lengthwise ofthe ring-rail, varying sufficiently diagonally to allow the car on onesupport to lap beyond the ear of the next support and economize theroom. The endless belt a is carried along both on the inner sides andouter sides of the whirls d d the whole length of the ring-rail'and makeone or more turns around whirls e e, one at each end,held in adouble-forked clasp P, attached to the ends of the ring-rail. The whirlse e are fitted to slide easily on vertical shafts S S, which cause thewhirls to turn by means of splines 25 25, fast in the shafts and groovesmade in the pulleys to receive them.

By reference to Fig. 2 itwill be seen that the belt a is held up closeto the whirls cl on the ring-holders by means. of deflector-whirls 'v1;, held on supports attached to the ringrail and placed between therings alternately on each side of the rail. These deflectorwhirlso carrythe belt in far enough between the whirls d on the ring-holders and,exerting equal pressure on both sides of theringholder, cause it torevolve freely in its support without pressing it against its bearing oneither side. This avoids one difliculty found in those plans in whichthe rings are driven by the bands from the cylinder,whieh drew them overto one side so hard that they would not always revolve because of thegreat friction in the ring-bearings. A tightening device is attached tothe back of the ringrail through which the belt 72. passes to keeptight. It consists of a forked frame m, held by screws through its twofeet to the inner side of the rail, and a hollow hub f, which is madelarge enough inside to receive an open spiral spring 2', and a rod h,carrying a whirl g in a fork in its inner end, passes through thespring. The outer end portion of the rod 71 has a screw-thread made onit, and a milled washer-nut y is fitted to screw on the rod h, and acheck-nut b is fitted to screw on the rod outside the washer andprevents the latter from turning when set. Two smaller whirls j areattached to the rail inside the tighteningframe (in the same way as thewhirls 'u are) to guide the belt n to and from the whirl g as it passesthrough the tightener. The vertical spline-shafts S are held at theirlower ends in bearings attach ed to a yoke Y, which is bolted to thelower rail C, and at their upper ends by a bearing G, bolted to theroller-beam F. The lower ends of these vertical shafts S havebevel-gears B made fast in them, which engage in like bevel-gears faston its outer ends of the horizontal cross-shafts H, held in bearings onarms extending out from the yokes y, and bearings attached to the endframe. The bevel-gears B on the inner ends of the shafts H H on eachside engage with like bevel-gears fast on a horizontal center shaft R,that is held at each end in bearings that are attached to the end framesA. At one end of this center shaft B it projects outside of the endframe and has a gear L attached to it that engages with the gear N, thatreceives mo-.

tion from the gear B through the gear on the cylinder or main shaft andthe gear 0'.

The operation of the improvements is as follows: The power to revolvethe rings is received from the main shaft through the gears O RN" L bythe center shaft R, and is conveyed to the side cross-shafts through thebevel-gears B and from the cross-shafts to the vertical shafts S S andthe whirls e,which slide up and down on their shafts to follow themotion of the ring-rail J from the whirls e by the endless belt at,which passes along each side of the whirls d on the ring-holders betweenthem and the deflector-whirls, giving a rotary motion to the rings. Theoper: ation of the belt-tightener is to draw out the bight of belt thatis held around the whirl g when the nut y is screwed farther in 011 therod h, and the spring 1' gives the belt at a proper tension at alltimes.

Having thus described my improvements, I claim as my invention 1. Inaspinning-frame, the combination of a ring-rail, a revoluble ring, aholder for said ring, a whirl attached to said holder, a supportattached to the ring-rail to carry said ring-holder, a belt to drivesaid ring-holder, a series of deflector-whirls held by said ringrail andarranged to carry the belt in between the ring-holder whirls, verticalend shafts, whirls secured thereon, and means for driving said endshafts, substantially as described.

2. In a spinning-frame, the combination of a ring-rail, a revolublering, a ring-holder,

a whirl attached to said holder,a belt, and

whirls to deflect said belt between said whirls on the ringholders,substantially as described.

3. In a spinning-frame, the combination of a ring-rail, abelt-tightening device consisting of a frame fastened to said ring-rail,a hub at the outer end of said frame, a spiral spring held in saidframe, a rod passing through said spring, a whirl held in one.end ofsaid rod, and a screw-nut fitted to screw 011 the outer end of said rod,substantially as described.

In testimony whereof I have hereunto set my hand.
